The world's lithium demand is currently increasing due to its use in batteries and green energy technologies. As a consequence, Li has recently been added the list of critical materials Europe. Finding new deposits necessary order guarantee mid- long-term stable supply. Granites associated pegmatites are primary ‘hard-rock’ source for Li, where it present variety aluminosilicate minerals. light...

Dark brown porous ferrotapiolite is a dominant product of alteration in pseudomorphs after primary stibiotantalite from the lepidolite pegmatite at Laštovičky, western Moravia, Czech Republic. Two compositionally distinct varieties of ferrotapiolite were recognized, a volumetrically dominant Fe3+-rich phase and a very rare Sb-rich phase. Niobium-rich ferrotapiolite, with up to 17.51 wt.% Nb2O5 ...

As technological demand for materials with specific physical properties has increased, the importance of strategic metals cannot be ignored. Strategic metals are those materials that have high economic value, are used in a variety of applications, and have few or no viable substitutions; supply may face the risk of restriction due to various technical, economic, or social factors. Mainly due to...
